I’m hoping someone comes out with a new system for aiming.
‘Shoot like a pro. You too can now hit a ball with a stick into a 5 inch hole at 6 feet’
I was going to bring up Poolology, invented by BC21, Brian Christ. It really is an advancement in playing pool. The thing that sets this system apart is that it tells you the fractional aim point that will pocket two balls randomly placed on the table, given a normal amount of throw. The idea is to speed up the learning process for beginners so that they begin to recognize when the shot "looks right." When you master Poolology you no longer need it.
I'm not aware of anyone who has found such a simple relationship between the balls and the rails. I think it qualifies as a new advancement in the game.
